Stimulus
All living things respond to stimuli. A stimulus (plural stimuli) is a detectable change in the environment. It is the thing that provokes a response. This means that all living things react to changes around them. For example, if a human hears a loud, unexpected noise, they jump. The noise was the stimulus and the response was the jump.
Plants
Plants also react to stimuli though it is not as obvious as animals. Plants grow towards sunlight and follows it- it is responding to the stimulus of the sunlight.
Animals
Other forms of reaction to stimulas is when an earthworms burrows into the moss when it senses the light or when an animals' hearts beats faster when they are frightened or scared. Migration to another place is also a respond to stimuli because animals move according to the weather or climate conditions. Though it may seem funny, crying too is a form of response. The stimulus would be the pain and the response would be the crying.
